Toyota G engine

[strick]

The Toyota Motor Corporation G-family engine was a straight-6 piston engine produced from 1979. It is unusual in that only a single displacement, 2.0 L (1988 cc), was produced in this series. All were belt-driven OHC engines, with multivalve DOHC and even variable valve timing added later.

These engines were used as a lower-displacement alternative to the more-common M family straight-6.

1G

Since just one displacement was offered, all G-family engines are marked 1G and share the same square 75 mm (2.95 in) bore stroke.

Applications:

• Toyota Soarer
• Toyota Celica Supra
• Toyota Crown
• Toyota Cressida
• Toyota Altezza

1G-EU

The Japan-spec 1G-EU was produced from 1979 through 1986. This is the only 2-valve SOHC member of the family. Output was 105-125 hp (78-93 kW) at 5400 RPM and 116-127 ft.lbf (157-172 Nm) at 4400 RPM.

1G-FE

The DOHC 1G-FE used a narrow valve angle and other fuel economy optimizations. It was introduced in 1988. Output was 135 hp (101 kW) at 5600 RPM and 130 ft.lbf (176 Nm) at 4400 RPM until VVT-i (introduced in 1998) bumped output to 160 hp (119 kW) at 6200 RPM and 148 ft.lbf (200 Nm) at 4400 RPM for the Toyota Altezza/Lexus IS200, Toyota Crown, Toyota Chaser, Toyota Mark II, and Toyota Cresta.

1G-GEU

The 4-valve DOHC 1G-GEU was intended for high performance. Produced from 1982 through 1986, mostly for the Japan market, output was 140-160 hp (104-119 kW) at 6200 RPM and 120-134 ft.lbf (162-181 Nm) at 5600 RPM.

Applications:

• Toyota Crown
• Toyota Soarer
• 1982-1986 Toyota Celica XX (Japan)
• 1983-1988 Toyota Mark II/Chaser/Cresta

1G-GE

1G-GE replaced 1G-GEU in 1988. It was detuned from 160hp down to 150hp and served the same cars as 1G-GEU did. It was produced for Supra GA70 till 1993.

1G-GZE

The 1G-GZE was a supercharged version produced from 1986 till 1992. Output was 168 hp (125 kW) at 6000 RPM and 167 ft.lbf (226 Nm) at 3600 RPM. Like the turbo, it was a 4-valve DOHC engine. 1G-GZE was mated only with automatic gearboxes. In August 1990 it was replaced with 1JZ-GE on Mark II/Chaser/Cresta, while serving on Crown till 1992.

Applications:

• Toyota Crown GS120, GS130
• 1988–1990 Toyota Mark II/Chaser/Cresta GX81

Então os motores dos LEXUS IS200 já vêm de 1979????

É verdade, foi com base nessa informação que procurei isto e fiquei parvo. Contudo no site onde vi essa informação dizia:

"The superbly glossy Lexus IS200 gracing the spotlit, inner-city, new car showroom floor; and the daggy old, unloved and unwanted 1G Toyota sixes pushed to one side at the outer suburban wreckers. Take a deep breath folks - the Lexus IS200 runs a 1G-FE engine, all iron block and uninspiring 114kW at just 6200 rpm. Yes, you read that right - a Toyota six that fundamentally dates back what - fifteen, maybe even twenty years? Oh s-u-r-e, the 1G under the IS200's bonnet does have intake cam variable valve timing and a variable length intake manifold, but putting a few jewels on an old bag doesn't make for a scintillating beauty, does it?"
